HIV-infected drug users (DUs) remain a target population as they represent a significant vector for the transmission of new HIV infections (Avants et al., 2004; Margolin et al., 2003), which occur through preventable drug- and sex-related HIV risk behaviors. Though numerous evidence-based HIV risk reduction interventions are now widely available as complete intervention packages, few evidence-based interventions have been designed for implementation within common drug treatment community-based organizations (CBOs), such as methadone maintenance programs (MMPs), where many high-risk HIV-infected drug users seek treatment. Moreover, the few evidence-based interventions that are applicable to drug treatment CBOs are not designed to be "community-friendly" and, hence, are unlikely to be implemented as intended or durable within these critical settings.
